CSIRAC


CSIRAC (/ˈsaɪræk/; Council for Scientific and Industrial Research Automatic Computer), originally known as CSIR Mk 1, was Australia's first digital computer, and the fifth stored program computer in the world. It is the oldest surviving first-generation electronic computer (The Zuse Z4 at the Deutsches Museum is older, but was electro-mechanical, not electronic), and was the first in the world to play digital music.
